The Covered Species Stack dataset shows the combined modeled distribution of 37 covered plant and animal species within the Desert Renewable Energy Conservation Plan (DRECP) study area. For each species, Biological Goals and Objectives (BGOs) and Conservation Management Actions (CMAs) were developed. Applicants may seek permits for “incidental take” resulting from renewable energy and transmission projects using the BGOs and CMAs as requirements.

The Other Species Stack dataset shows the combined modeled distribution of 55 non-covered species (2 planning species and 53 other species of interest) within the DRECP study area.

Both of these datasets employ a special tool which enables the user to view the combined modeled distribution of species in a single dataset, rather than simultaneously viewing 37 (covered) or 55 (non-covered) datasets individually. The composite datasets are made up using a 4km x 4km reporting unit.

To access the tool and view species distribution information, open the dataset of your choice, click on the identify tool and select a reporting unit. Then click on the number of records label in the pop-up panel. A scrollable list of species is provided with detailed information for each record.

All species records include links to the Biological Goals and Objectives (BGOs) for that species. Biological goals express the broad, intended outcomes of the plan. Biological objectives are specific, measureable outcomes expected as a result of the DRECP. BGO’s can also be downloaded as a PDF.

From the same pop-up panel, users can add specific species distribution datasets to the map or a dataset of terrestrial landscape intactness for the same modeled distribution area. Adding one or more of these datasets help the user examine the overall context for any selected species and the relative condition of its expected occupancy.

The species stack tool also includes a link to the species of choice to the Encyclopedia of Life, which provides additional natural history and status information.

The following 55 species are included in the other species stack (planning species are shown in bold). Note that the species in the non-covered stack do not represent a complete list of non-covered species in the DRECP study area, but rather those species having distribution models that were vetted and approved.
